Product Use

This Solid State Opto Isolated Relay is especially developed for Automotive use as a bi-directional servo switch.

Low current (Typically 10 to 15 milliAmperes) through the Relay LED Opto-electronically switches ON a High current Load (up to 4A).

In constant ON applications it can carry up to 4 Amperes, while in pulsed applications up to 9 Amperes may be switched momentarily.

These devices have been reliably used since 2015 in following applications:

• Audio Equipment
• Power Supplies
• Power Distribution
• Instrumentation
• Active Battery Balancing

Features

• Solid State = NO moving parts
• Single Pole, Single Throw (Off/On, Normally Open)
• Operating / Releasing Time ≤ 5 ms / ≤ 2 ms
• LED Control Current 10mA @ 2VDC
• Bi-Directional Current Flow
• Load Voltage: 40V Maximum
• On-Resistance: 0.05 Ohm Maximum
• I/O Breakdown Voltage: 1500Vrms Minimum
